<h3 id="ASYMMETRIC-ENCRYPTION"><a href="#ASYMMETRIC-ENCRYPTION" class="headerlink" title="ASYMMETRIC ENCRYPTION"></a>ASYMMETRIC ENCRYPTION</h3><p>Also known as public key cryptography. A cryptographic technique that uses two related transformations, a public transformation (defined by the public key) and a private transformation (defined by the private key). The two transformations have the property that, given the public transformation, it is not computationally feasible to derive the private transformation.   A system based on asymmetric cryptographic techniques can be an encipherment system, a signature system, a combined encipherment and signature system or a key-agreement system. With asymmetric cryptographic techniques, there are four elementary transformations: sign and verify for signature systems, and encipher and decipher for encipherment systems. The signature and the decipherment transformation are kept private by the owning entity, whereas the corresponding verification and encipherment transformations are published. There exist asymmetric cryptosystems (e.g., RSA) where the four elementary functions may be achieved by only two transformations: one private transformation suffices for both signing and decrypting messages, and one public transformation suffices for both verifying and encrypting messages. However, this does not conform to the principle of key separation and, where used, the four elementary transformations and the corresponding keys should be kept separate.</p>
